Kate Andrews insists it isn't "particularly surprising" Donald Trump has defied expectations in the US Presidential race.
The billionaire businessman is now the 'presumptive' candidate for the Republican nomination after rival Ted Cruz dropped out.
Trump has led a campaign which has courted controversy. Notably, he promised he would build a wall along the length of the border with Mexico and called for "a complete and total shutdown" on Muslims entering the United States.
Andrews, who is the news editor for Republicans Overseas, says Trump's success isn't unexpected given the political climate in the United States.
"Gridlock in Washington is as bad as I can ever remember it being," she told Julia Hartley-Brewer. "The Republicans have been promising year upon year to repeal Obamacare if they're given the house [of Representatives] and the Senate.
"Voters did both of those things, and still not much has changed. They're very angry across the board at politicians, so it's not particularly surprising Donald Trump had done so well."
Andrews explained how Trump has played on peoples' frustrations to get ahead in the race.
"There's no doubt he's been talking to a lot of people who are very upset," she added. "I don't think they want to talk about compromise or the nitty-gritty technicalities of how one makes policy.
"They want to talk about overthrowing the entire system."
